medium Nessus Plugin ID 77087
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote service is affected by multiple vulnerabilities.

Description

According to its banner, the remote web server uses a version of OpenSSL 1.0.0 prior to 1.0.0n. The OpenSSL library is, therefore, affected by the following vulnerabilities :

- A memory double-free error exists related to handling DTLS packets that allows denial of service attacks.
(CVE-2014-3505)

- An unspecified error exists related to handling DTLS handshake messages that allows denial of service attacks due to large amounts of memory being consumed.
(CVE-2014-3506)

- A memory leak error exists related to handling specially crafted DTLS packets that allows denial of service attacks. (CVE-2014-3507)

- An error exists related to 'OBJ_obj2txt' and the pretty printing 'X509_name_*' functions which leak stack data, resulting in an information disclosure. (CVE-2014-3508)

- An error exists related to 'ec point format extension' handling and multithreaded clients that allows freed memory to be overwritten during a resumed session.
(CVE-2014-3509)

- A NULL pointer dereference error exists related to handling anonymous ECDH cipher suites and crafted handshake messages that allow denial of service attacks against clients. (CVE-2014-3510)

Solution

Upgrade to OpenSSL 1.0.0n or later.
